Answer (in brackets)
A couple of days ago I posted a picture of a custom bracket we had made on the new MultiCam CNC plasma cutter, with the opportunity to guess what it was for. The answer is to hold up our new gutters by the back patio. We got them up just in time as it has rained hard for the last two days. They work good! The brackets feature a series of hearts to match the trim on the rest of the house. The bare metal gutters and brackets will be allowed to acquire a rust patina over time.
